Saving color and depth frames

varsha_h_ — Mon, 24 Aug 2015 02:45:27 GMT

Hey all, I'm working on Intel RealSense SDK (R2). I want to save the image from Camera_viewer. I have worked till saving the frame to specific buffers and retrieving from the same. I want to know how to save those frames/images to a specified location/folder.

Here's my code:

PXCImage *colorIm, *depthIm;
for (int i=0; i<MAX_FRAMES; i++) {

       // This function blocks until all streams are ready (depth and color)
       // if false streams will be unaligned
       if (psm->AcquireFrame(true)<PXC_STATUS_NO_ERROR) break;

// retrieve all available image samples
PXCCapture::Sample *sample = psm->QuerySample();

       // retrieve the image or frame by type from the sample
       colorIm = sample->color;
       depthIm = sample->depth;

       // render the frame
       if (!renderColor->RenderFrame(colorIm)) break;
       if (!renderDepth->RenderFrame(depthIm)) break;

       // release or unlock the current frame to fetch the next frame
       psm->ReleaseFrame();
   }

I'm able to retrieve the frames/images successfully, but I want to save those files for further use. So I want to know how to save those files in a folder.

Thanks in advance

The CaptureManager has a

The CaptureManager has a SetFileName method that will let you record to a file. There's an example in the SDK documentation you might find helpful:

void RecordORPlayback(pxcCHAR *file, bool record) {

// Create a SenseManager instance

PXCSenseManager *sm=PXCSenseManager::CreateInstance();

// Set file recording or playback

sm->QueryCaptureManager()->SetFileName(file,record);

// Select the color stream

sm->EnableStream(PXCCapture.STREAM_TYPE_COLOR,640,480,0);

// Initialize and Record 300 frames

sm->Init();

for (int i=0;i<300;i++) {

// This function blocks until a color sample is ready

if (sm->AcquireFrame(true)<PXC_STATUS_NO_ERROR) break;

// Retrieve the sample

PXCCapture::Sample *sample=sm->QuerySample();

// Work on the image sample->color

...

// Go fetching the next sample

sm->ReleaseFrame();

}

// close down

sm->Release();

}

Thank you so much. Do i have

@Dan

As you have suggested I have tried the same using a function. But I'm not able to record the frames to a specified folder. I have attached the file, please correct me if I'm wrong

hey!

hey!

how can I apply the same for librealsense?

I am trying to use:

RS_STREAM_COLOR_ALIGNED_TO_DEPTH

for getting something similar to the example in cpp-align

thanks
